LUBRICATING-CUP.

Specification. of Letters Patent.

Application led March 13, 1911, Serial No. 614,123. Renewed February 23, 1912. Serial No. 679,496.

To all whom it may concern:

Be it known that I, CHARLES H. NEWHALL, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Lubricating Cups, of which the following is a specification.

My invention relates to lubricating cups adapted for use on stationary or movable bearings and the object of the invention is to rovide a construction by means of which the feed of the lubricant can be easily and accurately controlled without removing the cover of the cup.

My invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a top view of a lubricating cup embodying my invention, Fig. 2 is a side elevation of the upper portion of the cup, Fig. 3 is a vertical sectional view, Fig. 4l is a similar view taken on a section line at right angles substantially to the section line in Fig. 3, Figs. 5 and 6 are detail views of the feed valve, Fig. 7 is a top view illustrating a modified construction, Fig. 8 is a sectional view of the cup shown in Fig. 7, both designed for stationary bearings, Fig. 9 is a topview of a cup designed for movable bearings, Fig. 10 is a sectional view of the same.

In the drawings, 2 represents the cup having a nipple 3 at its lower end for insertion into a bearing and provided with a feed passage 4.4

5 is the cover of the cup, held in place by the ordinary bayonet slot 6 and pin 7.

8 is a rod projecting centrally through the cover and down through the passage 4 and adapted to bear at its lower end upon the shaft to be lubricated. This rod is preferably polygonal in cross section.

9 is the lower member of a valve having prongs 10 for holding it in place in the bottom of the cup, said valve having feed openings 11. l

12 is a disk adapted to fit upon the member 9 and rotate thereon and provided with feed openings 13 which register with the openings in the member 9. The member 9 is stationary and the disk 12 has a squared central opening 111 through which the rod 8 extends and upon rotating this rod the disk 12 will be moved over the surface of the stationary valve member 9 and open or close the ports or feed openings therein. Evidently these feed openings may be made larger' or smaller by the simple rotary adjustment of the disk 12 and in this way the feed of the lubricant from the cup can be controlled to a nicety.

For the purpose of ascertaining the position of the disk 12 and the size of the feed openings, I provide a plate 15 adapted to rest upon the cover' and having a squared opening 16 to receive the upper' end of the rod 8. The ends of the plate are bent downwardly to form T-shaped ears 17, the lower ends of the ears having shoulders 18 formed therein to engage the lower edge of the cover, and the upper portions of the ears bearing ou the milled surface of the cover and having dents or depressions 19 therein which prevent the plate from turning prematurely on the cover. A pointer 2O is formed on the plate and is adapted to move over a scale 21 marked on the cover. One end of the scale 21 represents the open position of the valve and the opposite end its closed posit-ion and the operator, by glancing at the pointer, can easily determine the position of the valve and the size of the feed opening. The rod is adapted to slide freely lengthwise through the valve and throuo'h the cover and is designed for use, therefore, on a stationary bearing where there will be no tendency to throw the rod out. of the cup.

In Figs. 7 and S a modified construction is shown which consists in providing a rod 22, circular in cross section, and provided with a collar 23 secured thereon and having seats for springs 24: which are mounted on the valve member 25. The collar has a slight vertical movement between these springs su'tlicicnt to allow the rod to work back and forth in the operation of feeding the lubricant. The plate 26 on the cover has springs 27 thereon which enter grooves 28 in a collar 29 that is secured to the upper end of the rod. This collar also has a slight vertical movement between the springs and whenever desired the rod may be pulled entirely out of the cup, the ends of both the springs 25 and 27 being outwardly turned to allow the insertion of the collars between them when the parts are re-assembled.

In Figs. 9 and 10 I have shown the cup adapted for a movable bearing. A cover 30 has an opening 31 to receive the lower end of a hub 32 that is secured to the rod. A flange 33 is formed on the lower end of the hub to engage the cover and prevent the rod from being thrown out of the cup in the movement ofthe bearing. A spring 34 is secured to the hub and has an end adapted to enter notches 35 in the cover and hold the rod against premature rotary movement, but permitting it to be rotated to open or close the valve, the spring 34 sliding` on t-he surface of the cover and dropping into the notches successively as the rod is rotated.

I claim as my invention:

1. A lubricating device comprising a cup having a cover and a feed opening, and a rod projecting through said feed opening and adapted to bear on the journal to be lubricated, and having a limited longitudinal movement, a valve mounted in said cup and comprising a stationary rand a movable member having feed ope-nings or ports, said rod moving lengthwise independently of said valve, and having a rotary movement therewith to regulate said feed openings.

2. A lubricating device comprising a cup having a feed opening and cover, a rod projecting through said opening, a rotary valve having' feed ports, said rod having a rotary movement with said valve to regulate said feed ports and a limited longitudinal movement independently of said valve.

3. A lubricating device comprising a cup having a feed opening and a cover, a rod projecting through said feed opening and having a limited longitudinal movement, a valve for closing said feed opening, said valve and rod having a relative vertical movement and a simultaneous rotary movement.

t. A lubricating device comprising a cup having a feed opening and cover, a rotary valve, said valve comprising a stationary disk or member having feed openings or ports, and a rotating disk resting upon said stationary disk and having ports to register with the ports in said stationary disk, a rod passing through said valve and feed opening and having a limited longitudinal movement, the rotation of said rod operating to revolve said movable disk and open or close said feed openings.

5, A lubricating device comprising a cup movable disk and close or open said feed A ports.

6. A lubricating device comprising a cup having a feed opening and cover, a rotating feed valve, a rod passing through said feed valve and through said cover and having a limited longitudinal movement and means mounted on said rod and adapted to rot-ate therewith, the position of said means on said cover indicating the open or closed position of said valve.

7. A lubricating device comprising a cup having a feed opening and cover, a rotating feed valve having ports therein, a rod passing through said valve to rotate the same, said rod having a limited longitudinal movement, a plate mounted on said rod and resting on said cover and having an indicating hand or pointer, and a scale provided on said cover and over which scale said indicator hand is movable by the rotation of said rod, the position of said indicator hand determining the size of the feed ports in said valve.

8. A lubricating device comprising a cup having a feed opening and cover, a stationary disk having spring tongues thereon adapted to bear on the wall of said cup in said feed opening, said disk having feed ports therein, a rotating disk adapted to rest on said stationary disk and also having feed ports, a rod passing through said disk and capable of rotation therein, the movement of said rod operating to rotate said movable disk and increase or decrease the size of the feed ports through said stationary disk.

9. A lubricating device comprising a cup having a feed opening and cover, a rod within said cup having one end projecting through said feed opening and adapted to contact with the bearing to be lubricated and having a limited longitudinal movement with the revolution of the journal, said rod also having a rotary movement-'and a valve normally stationary with the longitudinal movement of said rod but becoming operative with the rotary movement of said rod to open or close said feed openings.
